doubtedly typical infestum , the value of testudinarium as a 
distinct race remains a question. 
In the foregoing bibliography, I have not included Neu- 
mann’s references to A. testudinarium (1899; 1901; 1911), 
nor those of Krijgsman and Ponto (1931 ; 1932), since these 
authors may have confused more than one species under 
that name. Neumann (1901) synonymized with his testu- 
dinarium, Ixodes auriscutellatus Koningsberger (1900, 
Teysmannia, XI, pt. 1, p. 6) and later (1911) also Ambly - 
omma compactum Neumann (1901, Mem. Soc. Zool. France, 
XIV, p. 296 ; $ ; Sumatra ; no host) . The standing of these 
two names remains open to discussion. Robinson’s many 
locality and host records of testudinarium probably cover 
more than one species. In view of this fact the true 
distribution and range of hosts of A. infestum cannot be 
given. 
Hyalomma (?) walckenaerii Gervais 
Ixodes ivalckenaerii Gervais, 1842, Ann. Soc. Ent. France, 
XI, Bull. Seances, p. xlvii (off Rhinoceros; without de- 
scription) ; 1844, in Walckenaer, Hist. Nat. Ins., Ap- 
teres, III, p. 246, PI. XXXIV, fig. 11 (no sex; no local- 
ity, off a rhinoceros of unknown species). Neumann, 
1911, Das Tierreich, Lief. 26, Acarina, Ixodidae, p. 133. 
Amblyomma (?) ivalckenaerii Neumann, 1899, Mem. Soc. 
France, XII, p. 279. 
Gervais’ species is as yet unrecognized. Neumann merely 
suggested that it might have been an Amblyomma . The 
original description reads : “Corps roux-grenat, un peu plus 
pale en dessous, passant au roux-cannelle ainsi que les 
pattes qui sont allongees et fauves a leurs articulations; 
abdomen ride en dessous ; point de taches sur le dos ; denti- 
cules des machoires mediocres; palpes un peu velus mon- 
trant un pore terminal a leur dernier article; ouverture 
genitale au niveau de la deuxieme paire de pattes; hanches 
de la premiere paire bispinulees a leur bord posterieur; 
celles des autres simplement echancrees; stigmates dans 
une impression en fossette subreniforme a l’aisselle de 
chaque patte posterieure. Longueur du corps, 0.005 [m] ;
